Specification of Letters Patent.

Application filed June 3, 1904. Serial No. 211,061.

To aZZ whom it natty concern.-

Be it known that I, LANSING ONDERDONK, a citizen of the United States,residing at New York, in the county of New York, .State of New York,have invented certain new and useful Improvements in Seams for SewedArtlcles, of which the following is a description, reference being hadto the accompanying drawings and to the letters of reference markedthereon.

My invention relates to an improvement in seams for sewed articles, andparticularly to a seam of great strength or arrangement of threads andfabric adapted for finishing the edges of fabrics or for covering anduniting the raw edges of two pieces of fabric which may be afterwardspread out flat.

The invention consists in the matters hereinafter described, andreferred to in the appended claims.

The invention is illustrated in the accompanying drawings, in which-Figure 1 represents a sectional perspective view of a seam embodying myinvention. Fig. 2 is a top plan view of the same. Fig. 3 is a bottomplan View of the same and Figs. 4, 5, and 6 are views similar to Figs.1, 2, and 3, respectively, of a modification.

In the drawings, referring first to Figs. 1, 2, and 3, A A represent twopieces of fabric whose edges are superposed. Two upper threads are usedwhich have loops a a formed in them and passed down through the fabricsubstantially one behind the other, but on the under surface approacheach other, forming the two sides of a trian le, so that a third threadI) may pass through both loops and may pass up over the edge and lie onthe upper surface of the fabric and, as shown in Figs. 1, 2, and 3, maypass around a loop in the thread a, and the thread a between its loopswill lie across the loop in thread I).

In Figs. 4, 5, and 6 a modification is shown in which the loop of threadI) surrounds loop a, while it passes over the thread a between itsloops.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A seam for sewed articles, comprising a body fabric, threads havingloops passed alternately therethrough at points substantially one behindthe other, a locking-thread passing through each pair of said loops, andlying over the edge, and surrounding one or the other of said threads onthe upper surface of said fabric; substantially as described.

2. A seam for sewed articles, comprising a body fabric, threads havingloops passed alternately therethrough at points substantially one behindthe other, but lying on the under surface of the fabric, diagonal toeach other and with their points together, a third thread passingthrough both loops at their point of meeting, and lying over the edge,and surrounding one or the other of the threads upon the upper surfaceof the fabric; substantially as described.

3. A seam for sewed articles, comprising a body fabric, threads havingloops passed alternately therethrough at points substantially one behindthe other, a locking-thread passing through each of said loops and lyingover the edge and passing under one row of loops on the upper surface ofthe fabric, and. surrounding one of said threads on the upper surface ofthe fabric; substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
